I have a stx38 black deck, and i put a new drive belt on and it runs fine but now iam having trouble shifting gears., i have the brake in the whole way but it seems like its not enough. is there ans adjustment, all it does is put slack in the belt right!

I am attaching a scan of the adjustment procedures straight from the tech manual. Give it a try and see how you make out.
